Allow to append a FAT16 partition image when building an ISO in hybrid mode.
This allows to add an extra writeable partition for when the ISO is burned to USB.
This feature is experimental and disabled by default.

The EFI partition for hybrid ISOs does not reliably show on all Windows systems, so we cannot use our "hack" of writing the configurations/PDFs to it. Reverted instead to a sane-sized EFI partition which is used just for booting. Added a note to the README that some tools such as Rufus support an ISO-mode to add a writeable partition at burning-time.

It is more convenient to not have to search for configuration files in different directories, and also helpful to see the standard configuration files, so move all ShredOS configurations into board/shredos.

Helps GRUB find the ShredOS volume when it otherwise cannot (such as when the IMG is used with Ventoy in BIOS)

The all-in-one ISO works well and is the jack-of-all-trades, covering all imaginable systems and scenarios, so include that in the default build configurations.

This adds a configuration for a jack-of-all-trades ISO, which allows BIOS and UEFI booting, being written to CD/DVD-ROM and USB drives, as well as having a writeable partition when being used from an USB drive. It basically combines the functionality of all prior release versions into one single ISO (per architecture).

Additional configurations for the i586 builds were added, so that new users can easily build those targets without needing to change things around via "make menuconfig" (potentially triggering unwanted other changes, e.g. reset of GRUB modules).

The default configuration "shredos_defconfig" was amended to produce both the existing USB image (which allows writing PDFs to the USB) and the new hybrid ISO (which now allows BIOS+UEFI booting, as well as flashing to USB and burning to CD/DVD-ROM) in one build.
Additional configurations "shredos_img_defconfig" and "shredos_iso_defconfig" were added which only target either the existing USB image or the new hybrid ISO, for full flexibility.

The main purpose of this commit is to allow the developer
or tester the ability to specify /dev/loop0 .. /dev/loopn on the
kernel command line in /boot/grub/grub.cfg and /EFI/BOOT/grub.cfg
where n is unlimited, although it is recommended that no more
than 20-30 loop devices are specified. The loop devices are of a
fixed size alternating between 500Kbytes and 1 MByte in size. Due
to their small size you would typically select 500 or 1000 rounds
when testing. To create loop devices append the following to
grub.cfg nwipe_options='--nousb /dev/loop0 /dev/loop1 ... /dev/loopn'
loop devices should be sequential starting at loop0, any break in
the sequence will cause creation of loop devices to stop.
This commit also includes a ffmpeg module
+BR2_PACKAGE_FFMPEG_SWSCALE=y for creation of
videos of the display. This may be useful for creating
training material, youtube videos etc using the command
ffmpeg -f fbdev -framerate 30 -i /dev/fb0 output.mp4
Initial work was started on excluding the boot disc if
the following shredos_exclude_boot_disc is appended
to the kernel command line.
discs including Ventoy.
2. The delay ShredOS introduces while it waits for USB devices to initialise
previously printed a period symbol every second to show somethink was
happening, instead, it now counts down numerically from 30. Most USB
devices have initialised after about 10-15 seconds.
3. Two new kernel command line options are introduced. The first allows the
user to determine whether PDF, log and dmesg files are sent using tftp or
ftp protocols.
i.e shredos_config=ftp:192.168.0.2:/home/joe/ftpdata/:jo:488993d:d
4. The second kernel command line option is:
shredos_output=ftp:192.168.0.2:/home/joe/ftpdata/:jo:488993d:d which
determines where the nwipe config files are retrieved from on ShredOS boot
and saved on nwipe exit.
5. Added package openssh for sftp support
6. Added package telnetd which had inadvertently been removed on the last update.
